1) the water represents the blood. 2) the heart IS a pump . it is a double pump 3.) the right side of your heart recieves blood from the body and pumps it to the lungs 4) No, the blood will not flow properly in the heart .. and may have complications ..

1. It represents blood. 2. When you press the heart pump model the water goes out the jar. While the human heart when it pumps,it pumps the blood throughout the body. 3. It function as a pump because heart pumps the blood throughout the body. 4.No, obviously when the straw is blocked there is no water will flows up. And it will not function well.
